Experience

Provisioning System for a Phone, Internet, and Cloud Company (Development)

I have been working on this provisioning system for five years, adding ease of use, integrating new business areas, collecting and graphing more info from devices, replacing old systems with newer technologies, adding a REST API for a mobile app, and integrating external apps, such as QuickBooks or DocuSign.

I designed architecture and developed an ERP web application, sold as a SaaS product. Built from scratch using Ruby on Rails and ActiveScaffold, it's a multi-tenant application for horizontal scaling, supporting most newer features available on this kind of applications, such as recurring billing and automatic guided accounting.
